Do you just want the one line output, or the whole Release/Branch/Build & PNumber (adjusted)
I'm not too sure why you use cat $line > detail.txt at all. cp $line detail.txt would do, but you could eliminate this and just use $line in the next statement (and remove the cat there too):-
Code:
var=`awk -F ":" '/PNumber/ {print $2}' $line`
.... or even:-
Code:
grep "PNumber" $line | read zzz var
Although perhaps a little inefficient (and we've all done stuff like this) nothing seems to be 'wrong' apart from seaching for the PatchNumber strings rather than PNumber, but it just depends what you actually want to see.
If you have three files in your loop, what output do you want to get? You are probably very close already.
while read line
do
cp $line detail.txt
var=`cat detail.txt|awk -F ":" '/PNumber/ {print $2}'`
if [ $var == 00 ]
then
echo "stabilization.Build.2013"
else
echo "stabilization.PatchBuild.2013.$var"
fi
done < a.txt
Moderator's Comments:
Please use CODE tags for input and output/errors as well as code.
The variable var appears to be a string with a leading blank. Perhaps one of the other suggestions to get the value set will do the trick, but at worst we could use shell functions to remove the leading space like this:-
Code:
:
:
else
echo "stabilization.PatchBuild.2013.${var# }"
fi
:
:
This will trim a single leading space, if there is one. If you want to trim off everything up to the last space (in case you have more) you can use ${var## } instead, but beware if your variable really does contain spaces that you want.
